The FrameMachine II is an updated version of the original FrameMachine
and can also make use of the Prism 24 genlock. It also includes 1MB of
30ns RAM. The main improvements over the original version was support
for the AGA screenmodes, and importantly the AGA video slot, as found
in A4000 series machines. If the FrameMachine II is used in an A2000
then an optional adaptor may be required, because the A2000's video
slot is not inline with a Zorro II slot.
